Keep getting infected with virus even after formatting pc

Hello. I am having a pretty serious issue with a virus that keeps re-infecting my pc even after I format and reinstall Windows. I will try to provide as much detail as possible about my situation.

I have been dealing with this repeated infection for quite some time now and have tried a few different options for getting rid of it. When the infection occurs, a ton of Internet Explorer windows start to pop up on my desktop. I also get a message that says "C:\Program Files\Internet Explorer\IEXPLORE.EXE No such interface supported." All of the IE windows link to different websites, some in different languages but they are all spam-type websites. We use ESET NOD32 anti-virus here and this does prevent connection to some of these websites but it never seems to detect the virus before it infects my pc. I also have programs force close on me, my pc reboots by itself, and malicious executables appear in my startup folder (which I assume is causing all the IE windows to pop up).

Like I mentioned, ESET never seems to catch an infection beforehand. I have tried using Malwarebytes free trial and that actually does catch an infection before it does anything. However, Malwarebytes itself eventually becomes infected so it doesn't help after that. Malwarebytes usually identifes the virus as "backdoor.bot" and "trojan.banker."

Since I could not clean this infection the first time around, I then tried formatting my hard drive and reloading Windows 7. However, shortly after joining our network domain I became infected again. This has happened countless times since then (reformat, reinstall, join domain, infection). I am not sure how this infection is occuring because we have other pc's on our domain that do not experience the problems I am having.

If anyone can provide advice or guidance on how to resolve this I would most certainly appreciate it!

trojan.banker:

Trojan Banker is a Trojan which is associated with the Banload and Downloader.Banload Trojan. This harmful Trojan gains entry to its victims’ PCs through websites which employ drive-by download tactics and through bundled third party security downloads and updates. This Trojan was designed to monitor its victims’ PC activities, and report it back to its developers.
A large threat associated with Trojan Banker is its ability to steal its victims’ usernames, passwords and financial and sensitive information. What is more, this seditious Trojan opens various security holes in the system which paves the way for other malicious malware to gain easy entry into the system.

First, I would suggest that you change ALL passwords using a 'known clean' computer. Not the infected one.

If you have anything that you've saved on a flash/thumbdrive, that may be the source of infection.

Flush a bad DNS cache and restore MS's Hosts file:

Copy and paste these lines in Note pad.

@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0

Save as flush.bat to your desktop.
Double click on the flush.bat file to run it.Vista and Windows 7... right click the .bat file and choose to run as Administrator. Your computer will reboot itself.

Download DDS from one of these links:
Mirror 1 Mirror 2 Mirror 3

• Disable any script blocking protection
• Double click the dds icon to run the tool.
• When done, DDS will open two (2) logs:
  1. DDS.txt
  2. Attach.txt <--- will be minimized in the task tray
• Save both reports to your desktop.

Include the contents of both logs in your next post.
The scan will instruct you to post Attach.txt as an attachment.

Download Combofix from any of the links below, and save it to your desktop.<--Important

Link 3

Click on this link Here to see a list of programs that should be disabled.
The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
If your anti-virus or firewall complains, please allow this script to run as it is not malicious.
Next: Disconnect from the internet. If you are on Cable or DSL, unplug your computer from the modem.
Next: Please disable all onboard security programs (all running with back ground protection) as it may hinder the scanner from working.
This includes Antivirus, Firewall, and any Spyware scanners that run in the background.

• Double click combofix.exe and follow the prompts.
• When finished, it will produce a log for you. Post that log.

Note: Do not mouseclick combofix's window while its running. That may cause it to stall
Please be patient while the scan runs, at times it may appear to stall.
When finished and after reboot (in case it asks to reboot), it should open a log, combofix.txt.
After rebooting ensure your Security applications have been re-enabled.

IF CF won't run:
During the download, rename Combofix.exe to sVchost.exe

Hello. I followed your instructions and here is the combofix log. I should note that combofix did reboot my pc and upon reboot a ton of internet explorer windows opened so I believe I'm still infected. The log seems to indicate that but just wanted to let you know. Thank you for the continued assistance!
